Support multiple PL061 controllers. If platform gpio driver couldn't be
found, PL061 gpio driver will continue to load PcdPL061GpioBase as the
register base.
It could be compatible with the use case of current PL061 gpio driver.

The PL061 GPIO controller is a bit of an anachronism, and the existing
driver does nothing to hide this - leading to it being very tricky to
read.
Rewrite it to document (in comments and code) what is actually
happening, and fix some bugs in the process.

The idea is to keep ArmPkg responsible for the ARM architectural modules and ArmPlatformPkg
the ARM development platform packages (with their respective drivers).
ArmPlatformPkg: Reduce driver dependency on ArmPlatform.h
- Move some driver definitions from C-Macro to PCD values
- Unify PCD driver namespace
